Answer:
Height = 4.67 in.
You mentioned only 5 to solve
Step-by-step explanation:
5)
Volume = area of base × height
448 = 12×8 x height
Height = 448/(12×8)
= 56/12 = 14/3 = 4.67 in
Solution:
The volume of rectangular pyramid is given as:
Where,
l is length and w is width and h is height
From given,
v = 448
l = 8
w = 12
Substituting the values we get,
Thus height of pyramid is 14 units
Cost of 7 gallons=$24.50
Cost of 1 gallon=24.50/7=3.5
Cost of 15 gallons=15*3.5=52.5
Cost of 15 gallons will be $52.5
For 1 flavor there are 9 topping
Therefore, for 5 different flavors there will be 5*9 choices
No of choices= 5*9
=45
The answer is in the image
The total nom of code that can be used is equal to 5+3 = 8
y=2x+15
where y=Value of coin
x=Age in years
Value of coin after 19 years=2*19+15
=$53
Therefore, Value after 19 years=$53
It will provide an instant answer!
